Abstract:

Purpose – The nature and characteristics of critical success factors (CSFs) that influence success on public private partnership (PPP) arrangements on different project typologies vary between countries and regions. Studies confirm the lack of success on PPP approach on public housing project (PHP). The main challenge to PPP-PHP success has been identifying, analysing, categorizing and matching CSFs that are likely to influence the PPP-PHP outcome. The purpose of this paper is to identify the CSFs that influence PPP-PHP delivery in Ghana. This is premised on the theoretical implications that u

Abstract:

We consider a point process (PP) generated by superimposing an independent Poisson point process (PPP) on each line of a 2D Poisson line process (PLP). Termed PLP-PPP, this PP is suitable for modeling networks formed on an irregular collection of lines, such as vehicles on a network of roads and sensors deployed along trails in a forest. Inspired by vehicular networks in which vehicles connect with their nearest wireless base stations (BSs), we consider a random bipartite associator graph in which each point of the PLP-PPP is associated with the nearest point of an independent PPP through an e

Abstract BACKGROUND: Deficiency of ADAMTS13, vWF cleaving protease, is known to be associated with TTP and some other microangiopathies, but low levels were reported in other diseases such as ITP, DIC, lupus and other thromboses. Although inhibitory autoantibodies were demonstrated in TTP, the mechanisms underlying reduced levels of ADAMTS13 in other disorders remains unclear. We tested the hypothesis that ADAMTS13 is associated with cell membranes and derived microparticles, especially from activated platelet and their microparticles (PMP), which could modulate the enzyme activities of ADAMTS

In order to decrease energy consumption caused by the dense deployment of pico base stations (PBSs) in heterogeneous cellular networks (HetNets), this paper first analyzes the energy efficiency (EE) of two-tier HetNets and then proposes a method to maximize the network EE by adjusting the PBS transmit power.

Abstract It is demonstrated that the Pauli antisymmetry principle (PAP) is without influence in the π electron subspace of polyenes and (4n + 2) annulenes (n = 0, 1, 2...) as long as the hoppings are restricted to nearest-neighbour centers. Here the π electrons behave like a hard core bosonic (hcb) ensemble where fermionic on-site and bosonic intersite properties are combined. In 4n and (2n + 1) annulenes (n = 1,2, 3...) π electron jumps between the first and last ring atom lead to a Pauli antisymmetry-based destabilization.

The public–private partnership (PPP) based model for the execution of infrastructure projects originated from Anglo-Saxon countries and was initially used in 1977 by the United Kingdom (U.K). Since then, its popularity has increased worldwide. Earlier studies by researchers and many other professional sectors and departments have introduced PPP contracts into different execution modes like Build, Operate, and Transfer (BOT); Build, Own, Operate, and Transfer (BOOT); and Build, Lease, and Transfer (BLT), etc. All definitions of PPP contracts are different but have a few common characteristics a

To explore the expression and the diagnostic value of ADAM17 in pernicious placenta previa (PPP) combined placental accreta. A total of 148 PPP patients were enrolled and divided into 2 groups: 62 patients with placenta accrete (PPP with PA group) and 86 patients without placenta accrete (PPP without PA group). In the same period, 74 pregnant women without PPP who had undergone cesarean section were selected as controls. The levels of ADAM17 were detected by qt-PCR. Diagnostic efficiency of ADAM17 were evaluated by receiver operating characteristics curve. ADAM17 was higher expression in PPP p

Abstract:

A framework for particle tracking velocimetry at high particle densities (HD-PTV) based on a Gaussian Mixture Model (GMM) is presented. This new approach is validated by tracking synthetic particles generated for a generalized turbulent pipe flow defining the ground truth. For a step size per time step of δS = 14 px and a particles per pixel (ppp) density of 0.09 the framework tracks about 90% of the ground truth particles (percentage of matched particles, pmp) already after 9 time steps without generating any ghost particles. For a lower step size of δS = 7 px, corresponding to a higher tempo

The use of the Precise Point Positioning (PPP) technique has become very advantageous with the development of GNSS positioning technology. It is possible to get highly accurate position information without the need of any reference station data using the PPP technique. However, there are various factors that affect the accuracy of PPP solutions, including the initial phase ambiguity solution type, which can be fixed or float, atmospheric effects, observation length, used satellite systems, and used precise products.

Abstract:

While research and policy documents seem to equate public private partnerships (PPPs) to a &ldquo;marriage made in heaven&rdquo;, globally they have had flimsy impact on public service delivery. Such seem to be caused by myopic governance emanating from scattered PPP governance literature, lack of a clear PPP good governance overview, as well as overemphasis of PPP financing over the wider PPP governance aspects. Using scholarly documents through content analysis, this study therefore intended to identify and examine the elements of a PPP governance system, and thereafter provide strat

Abstract:

In recent years, public–private partnership (PPP), as an alternative strategy in the delivery of infrastructure services, has developed rapidly in China. However, the implementation of PPP projects differs significantly between provinces and municipalities. Using the implementation data of national PPP demonstration projects, this study employs spatial autoregression and a spatial Durbin model (SDM) to explore the spatial characteristics and driving factors of PPP projects across China. The results indicate that the PPP project implementation rate in China shows significant spatial clustering,

PPP using Kalman filter typically takes half an hour to achieve high positioning precision, which is required for small movements detection. Many dataset gaps due to temporary GPS receiver signal loss challenge the feasibility of PPP in GPS applications for kinematic precise positioning. Additional convergence time is needed before PPP reaches the required precision again. In this study, Partial parameters were estimated by using the position and ZWD as prior constraint. The solved partial parameters were applied to initialize the Kalman filter for PPP instantaneous re-convergence. A set of br

Although the PPP institutional framework started to get purposely and mostly formed in the first half of the 90s in Korea the PPP itself actually came into occasional practice even before, owing to some legislation, covering roadways and sea ports.

Abstract Background Light transmission aggregometry (LTA) is considered the gold standard for the evaluation of platelet function but is labor-intensive and involves numerous manual steps. Automation may contribute to standardization. Here, we evaluate the performance characteristics of a new automated instrument, Thrombomate XRA (TXRA), and compare it against a manual instrument (PAP-8). Materials and Methods Leftover blood samples from blood donors or patients were tested in parallel with identical reagents and in identical concentrations both manually using PAP-8 and automated on the TXRA.

Abstract:

The inhibition of triosephosphate isomerase (TPI) in glycolysis by the pyruvate kinase (PK) substrate phosphoenolpyruvate (PEP) results in a newly discovered feedback loop that counters oxidative stress in cancer and actively respiring cells. The mechanism underlying this inhibition is illuminated by the co-crystal structure of TPI with bound PEP at 1.6 Å resolution, and by mutational studies guided by the crystallographic results. PEP is bound to the catalytic pocket of TPI and occludes substrate, which accounts for the observation that PEP competitively inhibits the interconversion of glycer
